I These angular flanges have in theiredge-porplates 11 and screw-bolts 12. This fixation I ensures at thesame time that all prejudicial bending moments acting upon the chimneyare transformed into axial tensil or compressive stresses.

In chimneys ofthis 'ype the inconvenience makes itself felt which is dueto the freely exposed upper flange, that destruction by rusting beginsat the connecting joints of these flanges as shown in 5. The upper edgeof the chimney is therefore covered by a ring 13 designed to protect itagainst rain. Thisring'13, which is loosely mounted, consists of a flatring, bearing on the. upper edge of the chimney and of two extensions 14and 15. Fhe outer extension 14 isconical and designed to keep the;rain-water away from the chimney and the inner cylindrical extension 15is cylindrical and of such length that no rain-water can get at theinner surfaces of the upper. portions ofv the iron-plates of the Ichimney.

On the chimney shown in Fig. 1,- which is cylindrical, a platform 1 6'ismounted so that it can be raised and lowered. This platform 16"has aguard-rail 17. On the lower surface of the platform 16- double angularpieces 18 are fixed between which, on cross-bolts 19, groovedguide-rollers 21 are rotatably mounted. These guide-rollers roll withtheir grooves20 on the websof the longitudinal irons 8 (Figs. 6 and7)'-so' that the hoisting and lowering of the platform can be carriedvout free of disturbances;

With regard toeach longitudinal iron the platform is fitted with twoparallel "hearing pieces 22 being arranged in radial direction andformed for journalling a transverseiaxle 23 on which two bars 24 areloosely mounted. In the free ends of every two bars 24 a screwbolt 25 isfixed by means of which these bars 24 can be fixed on the webs of thelongitudinal bars 8 by inserting the screw-bolts 25 throughcorresponding holes 26 of said longitudinal bars. For each longitudinalbar of the chimney one bearing piece 22' with oscillatablc bars 24 andscrew-bolts 25 is provided. Any number of holes 26 may be provided inthe longitudinal bars, according to the distance between the differentworking positions in which the platform is designed to be held on thechimney.

Lugs 28 are arranged on the upper edge of the chimney or on arms 27extending from said upper edge, saidlugs being designed for pulleysblocks 29 hooked at the other end into come I sponding eyes 30 on theplatform.

The movable platform presents the advantage that it may be used alreadyat the buildwhen it is constructed,

as will be hereinafter by means of which the sections, designed forbuilding the chimney can be hoisted to be swung to above the sectionwhich has been fixed in position. The freshsection is then lowered onthe fixed section. I After the two sections have been connected the one.with the other by means of screw bolts 6, the blocks and tackles aredetached and suspended again in the lugsofitlieuppen edge of the sectionwhich has been last put in position. After releasing" the platform byremoving the screw-bolts 25, the platform can be hoisted again to besecured in the fresh position so that another'section canbe put-on.

When the chimney isfinished,,theplatform I remains the upper position,securedon the longitudinal bars 8, as shown in. Fig, 1'. The blocks andtackles mightbe removed to be stored to prevent premature destruction byweather and'wind.

up the blocks andtackles and hangsthersame on the upper edge.ofthechimnemwhereupon the'platform may be lowered to; the: ground afterthefix ationz-me ans have. been removed,

so thatthepainters". and the material can. be hoisted on theiplatform.to the top of the chimney. The chimney is painted as: usual from thetop-end towards the bottom end.

After the painting the platform is hoisted to the top-end of the chimneyand. secured in this position.

At the building of iron-plate. chimneys it has been found that-the outercircumference of the chimney is not accurately cylindrical, and that thecircumferenceof the chimney is not regular from the topto the bottom sothat the guide-rollers of the loaded; platform might not securely anduniformly bear against the longitudinal irons; The arrangements showninFigs. 9- to 11 are signed to avoid this inconvenience; The platform 16has on its lower side as many radial guide bars '31 as the-re arelongitudinal irons on the chimney,- the central webs of said guide-barsbearing on guide-rollers 32, mounted in double brackets3'3 guided bymeans of rollers 34 onv the longitudinal irons 8 of the chimney. Thebrackets 33 are'preferably double so that the rollers 32 and 34 can bemounted between the two brackets on rest loosely on the outer edge ofthe platform.

I For securing the platform in its-position the I free end of the arms37 are fixed to the corid I responding longitudinal irons 8 by means ofscrew-bolts engaging with the holes 26 of said longitudinal irons.

The hoisting and lowering of the platform is effected, as mentionedabove, by mean-s of blocks and tackles 29. A platform with thearrangements shown in Figs. 9 to 11 will be pulled downwards in itssecured position by the weight of the brackets, wherefrom results aninwardly directed weight-component, by the action of which the rollers34 of the brackets are constantly pressed tightly againstthelongitudinal-irons 8 so that any undesired turning of the platform isexcluded and the work can be carried out securely, even when a strongwind is blowing and when the outer diameter of the chimney is irregular.

I claim 1. An iron-plate chimney composed of several sections formingtogether a cylinder, comprising in combination with the sectionsconsisting each of several elements, longitudinal T-irons fixed byrivets in the joints of said section-elements, a platform surroundingsaid chimney, means for guiding said platform on said longitudinalT-irons, and means for securely fixing said platform on said chimney atany desired height.

2. An iron-plate chimney composed of several sections forming together acylinder, comprising in combination with the sections consisting each ofseveral elements, longitudinal T-irons consisting of profiled ironshaving holes in their web fixed by rivets in the joints of saidsection-elements so that they project radially over the outer surface ofsaid sections, a platform surrounding said chimney, means for guidingsaid platform on said longitudinal T-irons, and means for securelyfixing said platform on said chimney at any desired height.

3. An iron-plate chimney composed of several sections forming together acylinder,

7 comprising in combination with the sections consisting each of severalelements, longitudinal T-irons fixed by rivets in the joints of saidsection-elements, a platform surrounding said chimney, means for guidingsaid platform on said longitudinal T-irons, means for securely fixingsaid platform on said chimney at any desired height consisting ofbrackets fixed on the lower side of said plat form, pairs of link-armsrigidly connected to the lower side of said platform, a pair of guiderollers in each pair of arms adapted to run on said T-irons, and a pairof links connected to each pair of brackets adapted to be connected tosaid T-irons for securing said platform on said chimney at any desiredheight.

4;. An iron-plate chimney composed of several sections having flanges,screws connecting the flanges of the several sections, longitudinalT-irons fixed on said sections connected with each other and coveringthe longitudinal joint of said sections, a platform surrounding saidchimney and having radial slots, pairs of brackets fixed on the lowerside of said platform, rollers in the lower end of each of said bracketsrunning on said T- irons, rollers mounted freely rotatable near theupper edge of each bracket in the horizontal plane and designed to guidesaid platform, radial bars on the lower side of said platform restingupon said pairs of rollers, pairs of links hingedly mounted on saidbrackets and upwardly projecting through said radial slots of saidplatform adapted to connect said brackets to said T-irons and forautomatically adjusting said platform in radial direction.

5. In an iron plate chimney composed of several sections formingtogether a cylinder, in combination with said cylinder composed ofsections consisting each of several elements, longitudinal T-irons fixedon the joints of said section-elements having holes at suitable points,a platform surrounding said chimney and having radial slots and anaperture for a winch-rope, brackets connected to the lower surface ofsaid platform, link-arms pivotally connected to said brackets andextending through said radial slots in said platform, and means forfixing the ends of said link-arms in said holes ofsaid T-irons.

In testimony whereof I afiix my signature.
